Reconfiguration of server clusters

ABSTRACT

A method includes identifying a master template from a repository corresponding to one or more servers in a preconfigured cluster positioned at an edge location. The identifying also includes receiving an input from a user defining a new configuration set by the user. The identifying also includes changing one or more parameter values in at least one configuration profile references. The identifying also includes creating a new master template based on the one or more parameter values. The identifying also includes creating a new planned inventory file based on the new master template. The identifying also includes changing an existing configuration of the one or more servers in the preconfigured cluster during runtime, based on the new planned inventory file.

BACKGROUND

A server cluster is a set of servers that work together to be viewed as a single system. Unlike grid servers, server clusters have each node set to perform the same task, controlled and scheduled by software. The components of a cluster are usually connected to each other through networks, with each node running an operating system. Clusters are usually deployed to improve performance and availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability.

Edge computing is a distributed computing paradigm that brings computation and data storage closer to the location where edge computing is needed to improve response times and save bandwidth. Edge computing is a topology rather than a technology. The origins of edge computing lie in content delivery networks that served web and video content from edge servers that were deployed close to users of the web and video content. Edge networks evolved to host applications and application components at the edge servers, resulting in commercial edge computing services that hosted applications such as dealer locators, shopping carts, real-time data aggregators, and ad-insertion engines.

DETAILED DESCRIPTION

The following disclosure includes many different embodiments, or examples, for implementing different features of the subject matter. Specific examples of components, values, operations, materials, arrangements, or the like, are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. Other components, values, operations, materials, arrangements, or the like, are contemplated. For example, the formation of a first feature over or on a second feature in the description that follows include embodiments in which the first and second features are formed in direct contact, and also include embodiments in which additional features be formed between the first and second features, such that the first and second features not be in direct contact. In addition, the present disclosure repeats reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

Further, spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, be usable herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the FIGS. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the FIGS. The apparatus be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors usable herein likewise be interpreted accordingly.

In some embodiments, one or more clusters of servers positioned at an edge location that are pre-configured (e.g., containing already established configuration profile references) are reconfigured (e.g., to operate with one or more newly established configuration profile references) during runtime (e.g., while the configuration file is executing). Throughout examples of this disclosure, cluster, server-cluster, and servers are usable interchangeably, unless specifically stated otherwise. Reconfiguration or modification of an existing configuration is performed by obtaining an existing template from a template repository storing many pre-stored templates. A template is chosen from the repository that corresponds to the existing configuration parameters. Thus, changes made to one or more parameters based on a user's selection create a more efficient server-cluster template and are easily inserted into a new server-cluster configuration that replaces the existing server-cluster configuration. Further, a new template, based on the user's changes, is saved in the existing template repository for future use as a selectable template by the same user or another user. The newly created template further creates a planned inventory file that switches the server-cluster from an old server-cluster configuration to a new server-cluster configuration during run time.

In some other approaches, to make a change from preconfigured cluster parameters the source code is manually changed. When a user wants to make a change; even to a single parameter, the source code is manually changed and a complete source code release life cycle is performed in order to bring about the change. In some other approaches, Excel based inventory maintenance tools are available, but are difficult to manage and prone to errors. In some other systems, writing a new inventory file manually takes several hours for any reconfiguration. A repetitive process which has to be followed every time a change in configuration occurs. Manually writing a new cluster planned inventory is prone to human errors in the coding of the planned inventory file. Other such systems have an inventory file created again from scratch for new clusters. Increasing the chances of conflicts such as internet protocol (IP) address conflict.

In some embodiments, a server cluster reconfiguring system creates new templates, is configured to supply stored templates, and automates the creation of source code using the templates. A user may input one or more parameters (e.g., desired changes) from configuration profile references included in the selected templates that, in turn, create further new templates for reconfiguration purposes. Reconfiguration deployment of the newly selected template is performed using stored templates and updating parameter values in the stored templates. The stored templates reduce the labor necessary to create inventory files from scratch and no manual file updating.

In some embodiments, dynamic cluster reconfiguration is an option. Once a cluster is created, the effect on other existing server-cluster configurations creates a potential to reconfigure or change other existing server-cluster configurations (e.g., a domino effect where one change affects other systems). Pre-stored templates for reconfiguration of the clusters are usable in this situation. During runtime, when there is a reconfiguration at a preconfigured cluster, a user is able to use existing profile reference templates and change parameters based on configuration profile references in one or more of the profile reference templates. The changed parameters crate a new template and the newly created template is stored for future use. Further, a new inventory file is created that is usable by cloud services, such as BareMetal as-a-service (BMaaS) toll, to reconfigure the cluster. Bare-metal services are cloud offerings that are comparable to renting a raw, dedicated server from a managed service provider (MSP). Like traditional dedicated servers, bare-metal instances are not preinstalled with a hypervisor and provide raw access to the system hardware.

In some embodiments, a runtime configuration change is made to an existing preconfigured cluster while the cluster is actively being usable with old values. A runtime configuration made by a user creates a new template with new parameters and further creates a new inventory file. The new inventory file switches the configuration of the cluster pursuant to the new parameters. Further, the switching of the old configuration with a new configuration is performed during runtime and no shutdown is necessary. In some embodiments, a user submits an input request containing new parameters for reconfiguration of an already running cluster. A system then identifies templates corresponding to the existing cluster. The user then modifies the input parameters from the configuration profile references in the identified template and creates a new master template. The system creates a new inventory file as well as a new master template. The system then reconfigures the existing cluster by switching to the configuration corresponding to the new inventory file.

In some embodiments, a new template is created through modification parameters of existing master templates. The server cluster reconfiguring system is configured to use pre-stored or existing master templates for re-configuration of the clusters. During run time, when there is a reconfiguration requirement at a preconfigured cluster, the server cluster reconfiguring system is configured to use existing profile reference templates and change parameters in one or more of the profile reference template. The server cluster reconfiguring system is configured to receive the changed parameters, create a new master template, and store the new master template for future use. For example, when the server cluster reconfiguring system is currently using a predefined master template designed to create a cluster and/or configure a cluster for the first time, the same predefined master template is stored in a repository and is configured to be a ready to use again as a template. Whenever, there is a need to reconfigure a cluster of one or more servers, the reconfiguration is performed by receiving user inputs for changed parameters, changing the server cluster parameters in the existing master template, and creating a new master template having new set of parameter values. The server cluster reconfiguring system is further configured to create a new inventory file, which is used by BMaaS to reconfigure the cluster.

In some other approaches, when a user wants to change a runtime configuration, the user makes a change in the automation source code. This change in the automation source code follows the complete release life cycle of software to production that includes validation of the new source code in tests and this process generally takes a few-weeks' time.

In some embodiments, the template-switching system of this disclosure abridges the runtime change in configuration. When a user wants to make a change in any parameter, the user simply fills another profile template and creates a new data center template. Further, the next time the user wants to create a cluster, the user simply selects the new data center template the user created earlier. There is no manual changing of source code or even a need to inform a source code development team.

In some embodiments, predefined and pre-created templates are based off of the existing templates created for the first use of the cluster. Once another template is created in the reconfiguration process, this template is stored for possible future use. Making selection of reconfiguration templates efficient. Whenever a cluster of multiple servers is reconfigured the reconfiguration is performed by selecting a similar template to the preconfigured template currently usable, taking user inputs, changing parameters from configuration profile references in selected template, creating a new template based on the user's changes, and storing the new template for future use. The new template is then usable to create a new inventory file and reconfigure the cluster during runtime using the newly created inventory file.

In some embodiments, real-time reconfiguration of parameters use parallel instances of processes. Thus, when parameters need to be updated in three reference profiles, then parallel instances will be initiated to update the values parallel and create a final template which provides reconfiguration in real-time (e.g., a faster response, instead of waiting for each reference profile to be updated one by one).

FIG. 1A is a diagram representation of a server-cluster reconfiguration system 100, in accordance with some embodiments.

Server-cluster reconfiguration system (SCRS) 100 includes user interface (U/I) 102. System 100 includes processing circuitry 902 (FIG. 9 ) and also includes a memory 904 (FIG. 9 ) connected to processing circuitry 902 (FIG. 9 ), where the memory is configured to store executable instructions 906 (FIG. 9 ). Executable instructions 906 when executed by processing circuitry 902, facilitate performance of operations, including receiving, from a user 102, a new input request 104, at user interface 106, including new parameters for an existing preconfigured cluster. User interface 106 allows user 102 to input parameters related to configuration profile references that are being changed within the existing preconfigured cluster. Based upon the user's selection of a template to replace the preconfigured cluster template (e.g., a template similar to the template being replaced) and inputted parameter changes (e.g., configuration profile references such as, cluster profile 108, application profile 110, and BareMetal profile 112) a new template is created at data center template engine 114. Data center template engine 114 receives the user's template selection and inputted parameter changes to the configuration profile references and creates a new template to be stored in pre-stored templates database 116. Further, user 102 is able to select a desired template from the pre-stored templates database from user interface 106. Data center template engine 114 then modifies the identified and selected template, based on the user's inputted changing parameters received at configuration profile references 118 forwarded through user interface 106 and profiles 108, 110 and 112. Data center template engine 114, then creates a new master template based upon the user's changes to be stored in pre-stored templates 104. Further, data center template engine 114 creates a new inventory file that is usable by cloud services, such as BMaaS toll, to reconfigure the existing cluster.

User 102 interacts with user interface 106 and inputs a new template request. When a new template has been selected, user 102 is able to input new parameters, such as a change of one or more configuration profile references for reconfiguration of an already operating cluster. User interface 106 is where interactions between user 102 and pre-stored template database 116 occur. User interface 106 allows effective operation and control of SCRS 100 by user 102. In some embodiments, user interfaces are composed of one or more layers, including a human-machine interface (HMI) that interfaces machines with physical input hardware such as keyboards, mice, or game pads, and output hardware such as computer monitors, speakers, printers and other suitable user interfaces are within the contemplated scope of the disclosure. Additional user interface layers may interact with one or more human senses, including: tactile user interface (touch), visual user interface (sight), auditory user interface (sound), olfactory user interface (smell), equilibrial user interface (balance), gustatory user interface (taste) and other suitable user interface layers are within the contemplated scope of the disclosure.

User interface 106 interacts with pre-stored template database 116. User interface 106 presents user 102 with several graphical user interfaces (e.g., display pages shown in FIGS. 2A-2D) where user 102 is able to select a replacement configuration template, input or change parameters for each configuration profile reference including: cluster profile 108, application profile 110, and Baremetal profile 112. Further, user 102 identifies templates corresponding to the cluster that user 102 desires to reconfigure at user interface 106. Based on the user's selected template and inputted parameters data center template engine 114 creates a new template for storage in pre-stored template database 116 and an inventory file is automatically created for the reconfiguration process.

FIG. 1B is a flow diagram representation of a method 150 of reconfiguring a server-cluster, in accordance with some embodiments.

For purposes of the disclosure operations as discussed need not be performed in the order as discussed in this disclosure. Some operations are not listed for the sake of brevity. Unless specifically stated, the operations discussed in FIG. 1B need not be performed in the sequences discussed.

In method 150, at operation 152, user 102 provides a new input request. At user interface 106 user 102 begins a reconfiguration template process. Form here operation 152 moves to operation 154.

In method 150, at operation 154, user interface 106 allows user 102 to select a new template and possibly a template similar to the configuration template being replaced. In a non-limiting example, user 102 may want to select a configuration template similar to the to-be-replaced template to make the inputting of parameters efficient. From here operation 154 moves to operation 156.

In method 150, at operation 156, user 102 inputs any new parameters or parameters that have changed for the purpose of reconfiguration of an already operating cluster. As a non-limiting example, operation 156 receives an input from user 102 at user interface 106 defining a new configuration profile references. In another non-limiting example, user 102 updates parameters of the selected template possibly stored from the last time the same template was reconfigured. From here operation 156 moves to operation 158.

In method 150, at operation 158 data center template engine 114 generates a new inventory file from the crated new master template from operation 156. In a non-limiting example, operation 158 creates a new planned inventory file based on the new master template. For example, the inventory file source code is automatically created for the new inventory file and the new template is ready for use in reconfiguration. From here operation 158 moves to operation 160.

In method 150 at operation 160 SCRS 100 reconfigures the original preconfigured cluster by switching to the new configuration cluster corresponding to the new inventory file. In some embodiments, operation 160 changes the existing configuration of the one or more servers in the preconfigured cluster, based on the new planned inventory file. For example, operation 160 modifies an existing configuration of one or more servers in a preconfigured cluster positioned at an edge location during runtime.

Table 1 below show a non-limiting representation of parameters of configuration profile references in a template, in accordance with some embodiments.

Further, at box 228F input form 230 is requesting a parameter (3) for KICKSTART_URL (as shown in application profile). In some embodiments, this process is iterative until all parameter values are inputted. In some embodiments, parameters that are modified or changed. For example, user 102 has selected the same template as the last configuration and a few parameters have changed and thus user 102 need make a few changes as the template has retained all the previously inputted parameters. User 102 is able to input this parameter at box 238C. User 102 is able to click on the submit button when completed to save the cluster profile or hit cancel to remove any changes to the parameters.

In some embodiments, user 102 skips one or more of the requested parameters in each of input forms 210, 220, and 230. In some embodiments, user 102 modifies the parameters that are changing to replace the preconfigured cluster template.
